SCE4412 Drawn Cup Needle Roller Bearing (Open End)
The SCE4412 open-end drawn cup needle roller bearing is engineered for high-load, compact applications requiring precision and durability. Featuring a thin-walled, cold-formed outer ring, this bearing minimizes weight while maximizing radial load capacity. Its open-end design simplifies installation in housings with tight axial space constraints, and the needle rollers are precisely guided to ensure smooth rotation under demanding conditions. The hardened steel construction and optimized surface finish enhance wear resistance, making it ideal for high-speed or oscillating movements.

Key Advantages for Industrial Use
This bearing excels in applications where space efficiency and reliability are critical. The open-end structure allows easy integration into assemblies without complex machining, reducing production time and costs. With a dynamic load rating of 12.5 kN and static load capacity of 10.2 kN, the SCE4412 handles heavy radial loads in confined spaces, outperforming traditional bushings or ball bearings. Its pre-lubricated design ensures low maintenance, while the cage-free configuration minimizes friction and heat generation, extending service life in harsh environments like automotive transmissions or hydraulic pumps.

Typical Applications Across Industries
Widely adopted in automotive and machinery sectors, the SCE4412 is commonly used in gearbox assemblies, steering systems, and electric motor pivot points. Its compact profile suits small electric tools, robotics joints, and agricultural equipment where axial space is limited. In textile machinery, the bearing's ability to handle oscillating motions makes it a preferred choice for thread guides. Manufacturers also leverage its corrosion-resistant variants for food processing conveyors or marine equipment, demonstrating versatility across temperature ranges (-30°C to +120°C) and operational conditions.
